WebThe voltage surges are transient in nature, that means they exist for very short duration. The main cause of these voltage surges in power system are due to lightning impulses and switching impulses of the system. But over voltage in the power system may also be caused by, insulation failure, arcing ground and resonance etc. Webcertain load conditions [1]. Transient over-voltages (TOVs) are impulses and super-synchronous oscillations which last less than a couple of cycles. They will arise when the DG power within a secondary network exceeds its load while the network is isolated, as illustrated in Figure 2.1.
